  • Cement made from steel production by-product can lead

    Steel slag is produced by the conversion of raw iron into steel – around 125 million tons of it per year. Much of that is dumped and only a small portion used, in embankments.

  • About Us - Cement-Free, Carbon-Negative Concrete

    In our concrete, cement is replaced with steel slag—a by-product of the steel-making process that is often placed into landfills. Using a process called carbonation activation, CO2 is injected into the wet concrete to give it its strength. As a result, any product made using Carbicrete technology permanently sequesters CO2, while turning industrial waste (steel slag) into a high-quality ...

  • What is Slag Cement? (with pictures) - wiseGEEK

    26.04.2020  The molten slag is then diverted to a granulator where it is rapidly drenched with water until it turns into a raw material called granules. The granules are then cooled rapidly, which stops crystals from forming and instead creates a glassy, non-metallic product. These granules are then dried and ground to a suitable fineness for use as cement.
